This invention relates to ironing machines and more particularly to asafety derice for machines of this character.

In ironing machines of the type in whlch B a rotating feeding element orroller cooperates with an ironing element or shoe to feed the materialtherebetween there is danger that the hands or fingers-of the operatormay be fed between the feedingelement and the ironing element thereby8813101151); 1n uri and crushing these members.

. %lhe object of this invention is to safeguard the operator of anironing machine by preventing the feeding of the operators fingers orhands between the elements of the machine. Another object of theinvention is to provide means accessible from the front of the machinefor starting or stopping the machine motor.

Further objects of the invention Wlll appear from the following.specification taken in connection with the drawings, m which,-- Fig. 1is an end elevation partly in section of an ironing machine having asafety .device constructed in accordance with my invention. r

Fig. 2 isa front elevation of the safety device shown in Fig. 1, and

. .Fig. 3 is a sectional view taken substantially on line 33 of Fig. 2.

Briefly stated the objects of the invention by providing a member suchas a rod or bar positioned above the feed roller and between the tableand the ironing element, these members'being connected to a switch forcontrolling the driving motor. The safety device in this instance,therefore, is designed to cut oil the power from the feed roller beforethe hands or fingers of-the operator can reach the ironing element orare attained in the embodiment illustratedand the feed roller may beutilized and in the embodiment of the invention illustrated theseconnections comprise a worm 26 carried by the motorshaft and meshingwith a worm ear 27 carried by shaft 28, the latter sha being splined toa shaft 29. The shaft 29 is connected through a worm 30 andworm gear 31to the roller shaft 32.

Thesafety device com rises a rod or bar 33 which extends throughout thelength 'of the, roller 23'and is secured at its ends to arms 34 carriedby a shaft 35 mounted in the frame members 20. A stop 36 is carried byeach of the frame v the backward movement of the arms 34. The shaft 35has secured thereto an arm 37,

the lower end of which is slotted as shown at 38. A snap'switch 39 issecured to one of the frame-members and -is connected by wires 40 and 41to the motor 22. .A button or pin42 is carried by the switch 39 andextends into the slotted portion 38 of the arm 37. Any suitab switch maybe used and in the embodiment shown the full line position of the button42 indicates the closed position of the switch. 'When, however, thebutton is moved to the dotted line position upon the raising of the' bar33, theswitch will be opened and the motor will be stopped.

From the position of the rod 33 in close proximity to the surface of thefeed roller and between the table 21 and the shoe 24. it will be evidentthat the fingers of an operator would engage and raise this rod beforethey could pass between the feed roller and the ironing-shoe. The safetydevice, therefore, effectively prevents the feeding of the operatorisfingers into the-machine.

The rod 33 or arms 34 may be actuated, of course, to start or stop themotor at any time the operator desires and these parts therefore servethe pur ose of control means as well as of a safety evice.

Although one specific embodiment of the invention has been illustratedand described, it will be understood that the invention is capable ofmodification and that changes in the construction and in the arran mentof the cooperating parts maybe ma e without departing from the spirit orscope of the ilfigention as expressed in the following 0 11118.

members and limits 1e construction of' What I claim is:-

1. In anironing machine, a feeding element, an ironing element, drivingmeans for said feeding element, a safety device positioned in advance ofthe ironing element and adapted to be engaged and actuated by thefingers of the operator as they rest on and are fed by the feedingelement toward the ironing element and control connections betweensaidsafety device and said driving means, said control connectionsincluding an electric switch and positive operative connections betweenthe safety device and switch whereby movement of the device 15 away fromthe ironing element will open the switch and movement of the devicetoward the ironing element will close the switch.

2. In an ironing machine, a feed roller, a shoe, a rod above said rollerlocated in advance of the shoe, a motor-operatively connected to drivesaid feed roll and means in cluding a switch and operative connectionsbetween the switch and the rod whereby movement of the rod away from theroller will open the switch and movement of the rod toward the rollerwill close the switch.

In witness whereof, I have hereunto set my hand this 10th day of June,1921.
